Application filed March 24, 1924. semi No. 'ro1,4:w.

To all whom it may concern:

Be it known that I, JOHN O. GOLDEN, a citizen of the United States, and a resident of Portland, county of Multnomah, and State of Oregon, have invented anew and useful Improvement in Electroplating-out fit Cases, of which the following is a specification. I The object of my invention is to provide a case, preferably made of metal, in which allv of the apparatus and chemicals required for electroplating may be conveniently housed and carried, and so as to bereadily accessible; also to make this case of inexpensive construction. Y I

A further particular object of my invention is to provide a case with a removable wall with outstanding portions which pro vides a drawer-like closet in which the battery units may be housed and concealed; and to provide the cover or top of said closet with binding-posts projecting exteriorly, to the interior ends of which binding-posts the terminals of the battery units are connected. Also to provide a secret compartment in said closet'for precious metals; also toprovide a switch on the exterior of said closet, preferably on its top or cover, by which two or more battery units may be connected, thus to vary the strength of the electric circuit transmitted. Y

The details of the above mentioned features and other incidental features are hereinafter fully described with reference toxthe accomp inying drawings. i

In the drawings:

' T e cabinet (1, which my invention concerns, isprefera-bly made up of sheet metal and consists of abottom 1, sides a and a and back at. These portions are integral and their unconnected edges are rolled back and a reinforcing wire 6 is'placed therein to prevent the edges from buckling, and the rollededges' also eliminate any roughfiedges'. The door 4 lof the cabinet is hinged to the bottom a at e, the reinforcing wire 6 at that 'point' passing through hinged portions f and f on the hinged door (1 and the bottom a respectively. The sides (1 of the door are flanged inwardly and in closed position extend exteriorly of the sides a and entary sectional view onthe line 7-7 of a of the cabinet. The top 9 is hinged at it,

being provided with hinged portions 11 and the back a is provided with co-operating hinged portions 2" and the reinforcing wire 6 passes through these portions, to constitute a single connection between the to and the'back a, as it does between the 'ttom a and the door d. The top 9 is pro:

over the door ortion (1 when it is swung upwardly in c osed position. A look la is mounted on the top .9 and a latch is is rovided on the door 03 and thus when the cor d is swun up into position and the top 6 p is closed, t e lock 1: will engage the latch is and lock the entire cabinet. On the side a a horizontal retaining flange, m is mounted near the top having a vertical clip m, and

an L-shaped retaining an le Z is mounted on the interior face of the ottom a and ex tends partway up the back a of the coni tainer. The removable wall 11. is adapted to fitwithin the L-shaped retaining angle m, and in position, is adapted to engage with the horizontal retaining flange Z as shown in Fi -1. The removable wall n is'made up a horizontal partition n spaced sli htly from its lower edge u so asto provi e a thereunder, in which the drawer 0 may be carried. Vertical flanged members M, and n carried by the Wall 92 provide with the horizontal partition n a receptacle for the batteries 39. The vertical partition 11' is spaced a slight distance from one end a of the wall and a short horizontal partition a is placed therein which abuts against the vertical partition n. When the removable wall 11 is placed in position behind the re;- taining angle Z, the horizontal portionn defines a recess which is entirely concealed and in this recess the valuable products used in the electroplating process may be placed for safe keeping. Above the horizontal partition n an open topped recess is formed in which lacquer cans 9 may be placed. A hinged cover a covers the space between the vertical partitions n and n, and when in position in the. cabinet fits under and is held by the flange m, and covers the batteries 1). Wires p connect to termi-.

nals p which extend through-the cover n with the batteries and with each other, and thus when the cover n is down as shown in Fig. 1, the terminals'provide means for conducting the electricity to the binding posts i and r. A movable switch finger 17 connected to the binding, post r by a wire p, connects the binding post r.at the electric circuit -from the batteries p, and one of the connections p from the batteries 12 connects the binding post 7- thereto. Coiled connections s and 8, negative and positive respectively, are adapted to be fastened to the article to be plated t and the metallic anode u, and are of sufiicient length to permit these articles to be placed in the electroplating bath {1), which is held within the receptacle '0 on the heating element or stove w. The stove or heating element is preferably heated by an electric current which. is connected to some source of electrical energy through the wires 4. p

Between the removable wall at and the side a I provide an apertured receptacle y in which the bottles of the solution y may be held. I preferably provide formed portions a on the bottom a* of the case a which spaces the container .a slight distance from the floor, as shown in Fig. 7

I preferably provide a volt meter 2 on the inner surface of the hinged cover 9, which is provided with outstanding arms a and 2 The positive and negative connections .9 and s are of suflicient length so that the ends of these connections can be contacted against each of the arms of the volt meter .2 and thus the volt meter can measure the amount of current passing 'through these connections. I 1provide a hinged brace rod 2, which is ivota 1y connected to the top 9 and to the si e a, as shown in this figure.

The 0 eration of my device is as follows:-

Myca inet is not only adapted to act as a container for the materials and implements used in the plating process but also serves as a working cabinet during the plating o eration. It is to be understood that the ca inet I have shown is merely a portable cabinet used for gold and silver plating in the jewelry and dental trades. With the cabinet as shown in Fig 1, the cabinet is locked by placing the key in the lock is and lifting the cover 9 to upstanding position as shown in Fig. 1 andext'ending the brace 2 out wardly so as to hold the cover in this position. The front of the cabinet (1 is then swung downwardly until it assumes a horizontal position and forms an extension of the front a. The stove'can then be connected to some source of electricity by means of the connection a: and the receptacle u can be placed on the stove and a sufficient quantity of electroplating solution can be poured from the container y to cover the article to be plated. The'rotary switch p then contacts with any of the plurality of terminals 40 to get the desired voltage. As shown,

there are three battery elements whichare each of two volt stren h, thus, by connecting one element in series, the strength will be two volts, two elements four volts and three elements six' volts. The ends of the connections 8 and s are then contacted with the arms a and e to measure the strength of the batteries. If the batteries are ofv suflicient strength the article to be plated is placed in the solution as is also the anode u, and the deposit is made by the current passing through the solution. V

If it is desired to remove the battery elements for inspection or any other reason, the removable wall can be withdrawn outwardly from the back a of the case. The wall can be completely removed and when removed the cover n can be raised up and the conneetions inspected. When the cover is placed on the container again, the bottom edge n is placed inside of the, L-shaped flange Z and the cover n is closed tightly and placed under the flange m and moved backwardly into the case until the flange n is engaged by the clip m which forms a part of the retaining flange m. In this position the cover is held against inadvertent lifting and the removable wall section is held tightly in place. The drawer 0 in which the utensils are kept can then be placed in the recess below the partition n which is spaced slightly above the bottom 12 of the wall n. a
